1 Overview
The NuTiny-SDK-NUC442 is a specific development tool for NuMicro™ NUC442
Series. User can use NuTiny-SDK-NUC442 to develop and verify the application
program easily. The NuTiny-SDK-NUC442 includes two parts: NuTiny-EVB-NUC442
and Nu-Link-Me. The NuTiny-EVB-NUC442 is the evaluation board and Nu-Link-Me is
its Debug Adaptor. Therefore, user does not need other additional ICE or debug
equipment.
2 Introduction to NuTiny-SDK-NUC442
The NuTiny-SDK-NUC442 uses the NUC442JI8AE as the target microcontroller. Figure
2-1 shows the NuTiny-SDK-NUC442 for NUC442 Series, in which the left portion is
called NuTiny-EVB-NUC442 and the right portion is called Nu-Link-Me.
The NuTiny-EVB-NUC442 is similar to other development boards. User can use it to
develop and verify applications to emulate the real behavior. The on-board chip covers
NUC442 Series features. The NuTiny-EVB-NUC442 can be a real system controller to
design users’ target systems.
The Nu-Link-Me is a Debug Adaptor, which connects your PC's USB port to your target
system (via Serial Wired Debug port) and allows you to program and debug embedded
programs on the target hardware. To use the Nu-Link-Me Debug Adaptor with IAR or
Keil, please refer to the “Nuvoton NuMicro™ IAR ICE Driver User Manual“ or “Nuvoton
NuMicro™ Keil ICE Driver User Manual” for details. The two documents will be stored in
the local hard disk when each driver is installed.
